1·Methods: According to the mirror imaging symmetry principle, we assumed the skull as an entirety and design the localizer to measure the projections of zygoma and zygomatic arch.
方法：视头颅为一整体，根据镜像对称性原理，制成由面弓、滑动定位尺、轨限、耳杆和额托等附件构成的颧骨复合体骨折定量复位校正仪。
2·Objective: to assess the treatment result of reposition and fixation to orbital maxillary zygoma complex fractures.
目的：探讨眶上颌颧骨复合骨折复位固定的治疗效果。
3·Objective: to explore the method to construct three-dimensional finite element model for maxillary posterior-tooth area, maxillary sinus, zygoma and zygomatic implant.
目的：探讨上颌骨后牙区、上颌窦、颧骨及颧骨种植体的三维有限元建模方法。
4·Abstract: Osteoradionecrosis occurs more often in the mandible than maxilla, and rarely occurs in the zygoma.
摘要颌面骨的放射性骨坏死多发于下颌骨，少数发于上颌骨，而颧骨的放射性骨坏死非常罕见。
